What would a Pro X 310 Top end with a 72.5mm piston in it be worth? Comes with Head, jug, piston, rist pin, o rings. Basically everything you need to bolt on and go.

Has about 2 hours on it. It runs very strong, it has been ported said the previous owner, but im not sure who it was.

It feels like a Mid-Top port job, but it still pulls pretty hard on the bottom with the 34mm carb i have on it.
